That sauce required serious work to be good. As it's written, the sweet overwhelms the tang and savory. We added more vinegar, and water as it was reducing rapidly to get an acceptable flavour. After that it was delicious! Broccoli was done well before the chicken so next time I'll start it when half or more of the chicken is done. I emptied the oil and coating bits from the pan before returning the chicken, broccoli, and sauce. Used vegetable oil as I don't like sesame oil. Everyone loved this.
